EU referendum: Cameron deal talks continue through night

Talks on reform of the UK's place in the EU continued in the early hours after Downing Street said there was "real hard work to do overnight".

European Council President Donald Tusk said there had been "some progress" on the first day of the Brussels summit, but "a lot still remains to be done".
He began a series of meetings with David Cameron and other leaders in the early hours. Formal talks resume later.
Divisions on the proposed deal for the UK are said to be deeper than expected.
Number 10 sources say Mr Cameron and Mr Tusk left talks at 05:30 local time (04:30 GMT) and are due to return at 09:00.
During the second day of the summit later, Mr Cameron will seek to secure the deal he wants ahead of holding an in/out referendum on the UK's EU membership.
